IMPROVEMENT IN FASTENERS FOR MEETING-RAILS OF SASHES.

Specification forming part of Letters Patent No. 157,830, dated December15, 1874; application tiled December 18, 1873.

To all whom it may concern:

Be it known that I, WoonBURY STonnR HOW, of Cincinnati, Hamilton county,Ohio, have invented certain new and useful Improvements in Window andDoor Buttons, of which the following is a specification:

My invention consists essentially of a latch or button having one ormore projections which, by engaging in a pivoted arm or tumbler suitablynotched for that purpose, is securely retained in looking or eifectivecondition; and my invention in its more elaborate forms comprehends acatch or striker, under or behind which the heel of the button engages,and other features hereinafter set forth.

In the accompanying drawings, Figures 1 and 2 represent, in the lockedand unlocked conditions respectively, my button and tumbler in theirsimplestform. Figs. 3 and 4 represent the locked and the unlockedconditions of a slightly more elaborate form of my device, coupled withan engaging catch for the heel of the button, and also additionalengagements in the tumbler. Fig. 5 is an underside view of the sameparts in the locked condition. Figs. 6 and 7 show in the locked andunlocked conditions substantially the same device, but with the additionof base-plates for the catch and button, the catch being of a novel or adifferent form, and the button bein g provided with a spring. Fig. 8shows the same device, having a slightly dilfereut form of tumbler.Figs. 9 and 10 show in the locked and unlocked conditions substantiallythe same device, but comprising a slight modification of my tumbler.Figs. 11 and 12 show by a top and an inverted view the locked conditionof the same tumbler applied to a simple spring-button. Figs. 13,14, and15 show modifications of my catch.

A and B may represent, respectively, portions of a door-jamb, and of thecorresponding door, and A and B may similarly represent portions of themeeting-rails of a common sash-window. My button 0 is pivoted at D tothe door-jamb A, and has projecting from its upper surface three studs,E F Gr. My tumbler H is pivoted to the door-jamb at I. The shape of thistumbler is such that stud E in the act of locking impinges against theconcave edge h of the tumbler, pushes it outward, as per strong arrow,until it reaches the position shown in Fig. 1. By this time, the stud Fhaving passed the salient angle h of the tumbler, the button isefl'ectually locked, because any retrograde motion of it withoutmanipulating the tumbler inevitably brings the said stud F against theend h of the tumbler, and arrests its further motion. This effectuallyprevents the release of the button by any clandestine efl'ortas, forexample, by means of a thin blade inserted from without between the twomembers A and B, nevertheless the button may be easily unlocked by anyperson on the inner side, who shall just move the tumbler in thecontrary direction of the arrow, and simultaneously with this movementpush back the button to the position shown in Fig. 2. In this positionthe use of the stud G is seen, its office being to limit the backwardmovement of the parts. The stud F also serves as a handle. 0 and H, (seeFigs. 3, 4., and 5,) show modifications of my button and tumbler adaptedfor use as sash-fastening. In this form the stud E for moving thetumbler, and the stud F for interlocking therewith, are both on theunder side of the button, which latter has on its upper side a knob orhandle, L, and a lip, J, which latter engages behind the slopingsurface, 70, of a catch, K, so as to draw the two rails together, andclose the joint between them. The tumbler H has in this representationseveral locking-shoulders or notches, l 2 3 4, to effect the lockingwhen the button is by carelessness or obstruction left partially turned.

The form shown in Figs. 6 and 7 is slightly elaborated from the lastnamed in the following particulars: It may also have a spring, P, toretain 0 in either or both positions. In this form the button andtumbler, instead of being pivoted directly to the sash, are pivoted to abase-plate, X, which itself is secured by means of wood-screws to thesash. These screws may, however, as in the present illustration, also doduty as pivots.

Instead of the spring I? a tusk or projection, Q, (see Fig. 8,) may beemployed, in conjunction with the stud F, to hold the tumbler securelyto its unlocked position, or this office may be served by two tusks, QQ, adapted to coact with both studs E and F. (See Figs. 9, 10, 11, and12.)

The button shown in Figs. 11 and 12 may have a curved or volute spring,R, for the purpose of throwing it into the locked condition wheneverreleased.

The catch K is an improvement on the common catch K by my device of thebridge T, from wherein is given greater resistance to detaching force inall directions. K is for use directly upon the sash, in conjunction withG H. G H X. The catch K has a cam-plate, M, which projects from a base,N, said cam-plate serving the same purpose as the incline 7c in thepreceding illustration. It has, also, my

bridge or bar T, under which the heel of the button engages in thelocked condition.

The tusks or projections Q Q Q are represented as modifications of theindentations in the tumbler, and are not separately claimed as new, theintention being to adapt the shape Catch K has a base-plate for use with4. The combination of the button 0 and catch K, substantially as setforth.

In testimony of which invention I hereunto set my hand.
